Breath is life and change, a basic connection between the inner and the outer. It is a flowing bridge between life and death. Every breath is rebirth, inspiration, a letting go of the old. Breathing is a constant source of energy, a continuous affirmation.
Change your breathing and you will think differently, and this change can be created by choice because breathing is one of the few bodily functions that can be voluntary or automatic.
Here is an easy breathing exercise:
Fix your concentration in the middle of the forehead. See a radiant jewel there. Watch and observe what happens as you inhale through your nose - pulling your diaphragm in, and exhale through your nose - pushing your diaphragm out.
